Description
Technical field
The present invention relates to a kind of compressor, as preamble Patent right requirement 1 is described.
Background technique
Nowadays use the compressor of compressed refrigerant to be applied to a plurality of applications, such as be used on the very diversified commodity in (indoor) air-conditioning system and the refrigerating field.(indoor) air-conditioning system field refers in particular to the air-conditioning system at dwelling house and office building; With the air-conditioning system of Motor Vehicle (such as the air-conditioning system of passenger vehicle passenger compartment and the air-conditioning system in the load-carrying vehicle cockpit) with in the air-conditioning system (train, the air-conditioning system of tram car etc.) in track field.At refrigerating field, much more especially refrigeration compressor is applied to Refrigerated Transport (for example the chiller plant of the chiller plant of semitrailer truck, rail wagon etc.) and in static field, for example the refrigerating field (cold storage cabinet, supermarket and other banks refrigeration) in the supermarket.
Give one example, such as a refrigeration compressor that power supply unit is arranged, power supply unit is set in the power supply cabin, and power supply cabin (partly or wholly) is defined by the power supply unit shell that can be found in the passenger compartment field of refrigeration.Compressor in the passenger compartment is the compressor of wobbler pattern normally.In said type of compressor, it is to be installed in rotation on one to drive on the engine-operated live axle that power supply unit has a wobbler or supporting ring.
Wobbler or supporting ring are in piston is set at the cylinder thorax, so that realize the rotation of live axle, so the piston swept volume of compressor and quantity delivered can be affected.The quantity delivered of compressor and stroke of piston can be adjusted through the pressure distribution in the power supply cabin.In order to adjust or the control piston stroke; Said compressor has a low-pressure fluid passage; Low-pressure fluid passage feasible power supply cabin and a pumping chamber; Promptly a suction chamber is communicated with, and also has a high pressure fluid channel, and high pressure fluid channel makes the power supply cabin be communicated with a hyperbaric chamber (pressure chamber).In this way, freezing mixture can be provided in the power supply cabin through high pressure fluid channel, and the result who causes is that power supply cabin internal pressure has raise.Pressure in the power supply reduces through the low-pressure fluid passage.
Known wobbler form compressor is to use the compressor of lubricant oil.Rotatablely moving of wobbler, the motion mode of other mobile members and pressure change cause that the lubricant oil that is positioned at the power supply cabin is stirred and forms a kind of mist of oil (oil mist lubrication).The mist of oil that in the power supply cabin, forms gets in the suction chamber through low-pressure fluid passage (between power supply cabin and suction chamber), and gets in the cylinder from suction chamber with freezing mixture again.Mist of oil after overcompression partly returns the power supply cabin through high pressure fluid channel; This moment, the remaining part of lubricant oil was passed back in pumping chamber or the suction chamber through the refrigerant pipe of the chiller plant of a band compressor; (especially through be arranged in the refrigerant pipe cold and warm exchanger and with the form of condenser and vaporizer, and be arranged on ducted pervasion component through one and realize.),, pump into lubricant oil in the pipeline here in order to realize reliable lubrication effect.The oil mass of the refrigeration compressor of this type is injected to and approximately comprises 100 gram lubricant oil in every liter the refrigeration agent.
Also exist not with the type of compressor (for example constantly making the compressor of piston stroke) of wobbler, although above-mentioned compressor does not generally have the fluid passage between suction chamber and power supply cabin, lubricant oil gets into refrigerant pipe and gets back to the suction chamber of compressor therefrom.
The compressor that is used for passenger vehicle passenger compartment air-conditioning system is the product of producing in batches, when finding to have flaw, changes.Can not keep in repair.Likewise, do not safeguard in the service life of the compressor of said type.Yet at the compressor field with high relatively refrigeration work consumption, situation is really not so.Compressor on the passenger vehicle has relatively short service time, and bigger compressor for example is used on the bus or on the truck in REFC and the bank, in fact is in continual operation.Because operation for a long time, the periodic maintenance of compressor becomes most important.Change oil and also in the maintenance work of routine, carry out.If be full of lubricant oil in the refrigerant pipe, the old oil of part still is retained in compressor or the chiller plant in the process of changing oil.This will shorten engineering time at interval.In addition, from the energy aspect lubricant oil to be full of refrigerant pipe be imperfect; These shortcomings seem unimportant in passenger vehicle air-conditioning system field, but the situation of the compressor of larger volume can cause energy loss.
Summary of the invention
Correspondingly, an object of the present invention is to provide the effective compressor of a kind of cost, and have advantage with respect to existing technology from the angle of energy.
Above-mentioned purpose is through realizing according to the described compressor that is used for compressed refrigerant according to the present invention of claim 1.It is to be noted that here the present invention does not receive the restriction of wobbler compressor types.The present invention can be applicable in all reciprocating-piston compressors that can expect; The single in-line arrangement that for example has constant stroke of piston, the reciprocating-piston compressor of V-type or W type, axial piston compressor and radial plunger type compressor; And in the rotating cylinder type piston compressor that all can be expected; Screw type for example, rolling rotor-type, the compressor of screw type and spool type.
More technical characteristicss of the present invention are specialized in the dependent claims.
Description of drawings
Through following object lesson the present invention is done further description based on preferred embodiment and with reference to accompanying drawing, in the picture:
Fig. 1 is the structural representation of first specific embodiment of compressor according to the present invention.
Fig. 2 is the structural representation of second specific embodiment of compressor according to the present invention.
Embodiment
First embodiment shown in Fig. 1 is a swash-plate-type compressor 10.Said compressor has a power supply unit shell 12, to define power supply cabin 14 (crank box cabin).In power supply cabin 14, be provided with a wobbler 16.In another embodiment, wobbler 16 also can be supporting ring.Wobbler 16 is connected with piston 22 through live axle 18 rotary driving and through slide block (not shown in Fig. 1).Among first embodiment who is pointed out here that, compressor 10 has five pistons 22.In an alternative of the present invention, yet other any amount of pistons are conceivable.
Wobbler 16 and live axle 18 adopt the Placement of associating rotations; (do not show any more details among the figure by the mode that tilts or pivot; And indicate through a four-headed arrow 20) be hinged on the live axle 18, can adjust about the inclination (angle of inclination 24) of live axle through it like this.The quantity delivered of compressor can regulate or control according to the variation at the angle of inclination 24 between live axle 18 and the wobbler 16.It is big more that 90 ° angle is departed from angle of inclination 24; That is to say that the angle of inclination becomes more little; Quantity delivered is also just many more, and this is that cylinder thorax 26 is corresponding for one by one with piston because the stroke of piston 22 that is arranged in the cylinder thorax 26 becomes littler and becomes bigger along with angle of inclination 24.
Live axle 18 through one be set in the power supply unit shell 12, shape be annular, consider environment with waterproof mode seal the power supply cabin 14 sealed member 28 be arranged on the power supply cabin 14 in.Live axle 18 is installed in the compressor 10 with two tie points, and especially through a clutch shaft bearing 30 and second bearing 32 that is installed in cylinder block 34 that is arranged in the power supply unit shell 12, cylinder thorax 26 also is installed in the cylinder block 34.Defined by power supply unit shell 12 equally, compressor 10 is that fuel tank 36 is communicated with power supply cabin 14 fluids through hole 38.In the component in the fuel tank 36 and the cabin 14 that supplying power equally, there is one to be used for the oil sump 40 that compressor 10 lubricates.
First embodiment's having thus described the invention compressor 10 also has a cylinder head 42 that is limited in the disputer shell 44.In cylinder head 42, be provided with the pumping chamber 46 of a suction chamber or suction space formula.Pumping chamber 46 in addition, the pressure space of an anologue cavity, promptly hyperbaric chamber 48 is set in the cylinder head 42.As 50 indications of first arrow; Be about to compressed refrigeration agent and flow out pumping chamber 46, get in the cylinder thorax 26 after compression process through hole (suction valve sucks the aperture) (not shown); Refrigeration agent, above-mentioned for another example second arrow 52 is discharged from hyperbaric chamber 48.
Between power supply cabin 14 (as the oily guiding element of compressor 10) and pumping chamber 46, be provided with a first fluid passage 54 (among the described embodiment, consistent) here with the low-pressure fluid runner of swash-plate-type compressor 10.Be provided with an oil separator 56 at first fluid passage 54 places, among aforesaid first embodiment, be designed to a centrifugal oil separator and 66 and oil separator outlets 72 of an oil separator inlet are arranged.
Need point out that herein the oil separator of first fluid passage 54 flows into that part 58 does not need and is communicated with as power supply cabin 14 fluids of oily guiding element.In an alternative embodiment; First end 62 that oil is separated intake section 58 is communicated with (principle is that a those skilled in the art is familiar with this and in following second embodiment's description, will obtains more concrete description) that is to imagine with the low pressure chamber low pressure chamber fluid of low pressure chamber or refrigerating equipment, be provided with the compressor 10 as oily guiding element in the refrigerating equipment.This that is to say; In an alternative embodiment; What can imagine is; The first fluid connecting tube need not be consistent with the low-pressure fluid connecting tube of compressor 10, more properly is to form independent special-purpose fluid passage, and low pressure one side and the pumping chamber 46 of refrigerating equipment carried out fluid connection (through oil strainer 56).
In addition, compressor according to the present invention has one second connecting tube 74, and power supply cabin 14 realizes that through second connecting tube 74 fluid is communicated with (in first embodiment, being communicated with consistent with the high-pressure liquid of swash-plate-type compressor 10) with hyperbaric chamber 48.The second fluid connecting tube 74 has a transmission part 76, is communicated with hyperbaric chamber 48 fluids at first end 78.At second end 80; Transmission part 76 be be set at the second fluid connecting tube 74 in transmission part import 82 fluids of injection syringe 84 be communicated with; Injection syringe 84 is arranged in the second fluid connecting tube 74, or is communicated with transmission part import 82 fluids of Jet injector 84 in being arranged on the second fluid connecting tube 74.In addition, the second fluid connecting tube 74 has an exit portion 86 that has successively in first end 88 and second end 90.Here, first end 88 of exit portion 86 exports 92 fluids with an injection syringe that is set on the injector 84 and is communicated with, and second end 90 of exit portion 86 is communicated with power supply cabin 14 fluids.
Because power supply cabin 14 is communicated with (incessantly) with the hyperbaric chamber 48 of compressor 10 through the second fluid connecting tube 74 with through injector 84 fluids that are arranged on wherein, the work under the effect of successive pressurize refrigerant of power supply cabin 14.Flow into of injector nozzle 93 decisions or the restriction of the refrigeration agent dosage in power supply cabin 14 by injection syringe 84 from hyperbaric chamber 48.This is necessary because in order to adjust the power supply size of compressor 10, the pressure in the power supply cabin 14 must keep higher level (situation that depends on load) than the suction pressure that is distributed in the pumping chamber 46.
Pressure setting in power supply cabin 14 is to realize through the reduced cross-section of sentinel valve 100 and so on, and the oil that sentinel valve 100 is set at first fluid passage 54 separates outflow part 60, and is connected on the electrical adjustment equipment 101.If surpassed required pressure then sentinel valve 100 is opened, if required underpressure sentinel valve then be closed at the pressure of power supply in the cabin 14.Sentinel valve 100 among first embodiment is helical type conductivity cell valves of an eletromagnetic-operating, and helical type conductivity cell valve can be in associated electrical magnet 103 cuts out after through electric current.Among first above-mentioned embodiment, not that the pressure that distribute in power supply cabin pressure but the pumping chamber 46 start as one or Moderator Variable.It must be noted that here except 100, one apertures of sentinel valve (adjustable), a can regulate slide block or some other forms of valves also will flow out in the part 60 at the oil separator of first connecting tube 54 and become feasible.
The pressure that in power supply cabin 14, distributes with the result that the pressure that in pumping chamber 46, distributes varies in size is; The oil of refrigeration agent (when sentinel valve 100 is opened) through first fluid connecting tube 54 separates and flows into flowing in the centrifugal oil separator 56 with oil separator import 66 of part 58, when refrigeration agent is carried because flow condition and rotatablely moving of wobbler 16 cause the generation of mist of oil.When it flows into centrifugal oil separator 56; Gas is ready-made rotation status; The result of this variation is that the oil droplet in the oil separator shell 94 is collected the lower region of the centrifugal oil separator in oil droplet holds oil sump 96 because the oil droplet in the mist of oil that centrifugal force causes is dished out from oil separator shell 94.Hold the oil of oil sump 96 and stirred once more in order to prevent to be positioned at oil separator at oil drip the oil film of formation of the wall of oil separator shell 94; Centrifugal oil separator 56 has the impact thin slice of a T shape or mushroom-like or the striking plate 98 of T shape or mushroom-like, and the refrigeration agent that is set as rotation status and no longer has a mist of oil through above-mentioned striking plate with the direction deflection of oil separator outlet 72 and export the said centrifugal oil separator of discharge through said oil separator again.
In injector 84 or Jet injector; Fluid tip (transmission part) through being produced through transmission part import 82 entering injection syringes 84 produces pumping action;, pumping action causes and is inhaled into medium, is the oil (with refrigerant mixed) that produces from centrifugal oil separator 56 in this case; Suction medium import 102 through injection syringe 84 sucks, and quickens the back through injection syringe outlet 92 once more and discharges.About inhaling the oil that medium import 102 provides, the latter is communicated with carrying out fluid through three-fluid connecting tube 104 with the oil export 106 of centrifugal oil separator 56.Here; In the oil that transmits is supplied power cabins 14 through the power supply cabin import 108 that is provided with from second end, 90 entering of the exit portion 78 of the second fluid connecting tube 74; The cabin import 108 of wherein supplying power is set at lubricated each some zone of treating of compressor 10; In first embodiment, be described in wobbler 16 above, the latter just constantly is provided oil or oiling agent like this.In addition or under the selective situation; Also can expect in compressor, being provided with more power supply cabin imports 108; There is much more more power supplies cabins inlet oil (for example bearing) (in this respect, also can with reference to second embodiment according to the compressor of the present invention that describes below) to be provided to more lubricating point zones of treating more.
Because the oil through injection syringe 84 has the refrigeration composition or mixing contains or comprise refrigeration agent, behind the nozzle (diffusion section) that is arranged on through in the injection syringe, the refrigeration agent that is transmitted is cooled (because diffusion), and this causes the cooling of oil.As a result, the intensification phenomenon of power supply cabin 14 and power supply unit shell 12 is avoided or has been reduced.Content of the present invention comprises also that is accordingly carried out an oil cooled equipment in compressor.Foregoing is not limited to the compressor that has oil separator.What in fact, can expect is that compressor does not have oil separator that an oil cooling apparatus is but arranged.For example; What can expect is; Injection syringe 84 is not through oil separator (centrifugal oil separator 56) but through an oil pump a kind of oil-refrigerant mixture is provided, and wherein the oil as oiling agent has obtained cooling (mainly being as the result who transmits after refrigeration agent obtains spreading) at it in the proliferation part process of similar nozzle.The basic idea that realizes oil cooling apparatus in the compressor is not limited to use other proliferation parts arbitrarily of injector or some.Oil cooler or additive method through air-cooled, water-cooled or refrigerant cools mode make oil cooled oil cooler, can be set at any position of compressor oil pipeline, and this also can expect.
Mention above, also can from Fig. 2, find out, it must be swash-plate-type compressor that compressor does not need.Compressor 200 is Reciprocatory piston compressors of a single in-line arrangement shown in figure 2, based on vibration transfer principle operation and have constant stroke of piston.In the embodiment shown in Figure 2, compressor 200 has two pistons 202.Piston 202 operationally interconnects with live axle 18 through the connecting rod 204 that is installed on piston 202 and the said live axle.Self-evident, the quantity of piston 202 is not limited only to two.Any possible piston 202 quantity all are conceivable.
All are known from first embodiment by the parts that reference number indicates, and consistent with the outward appearance and the function of those parts among first embodiment, and above-mentioned parts like this will can not mentioned or be described once more in existing second embodiment.Difference between first embodiment and second embodiment can be set forth in ensuing part.
Compare with swash-plate-type compressor 10 (first describes embodiment); Second embodiment's compressor 200 has the first fluid connecting tube 254 of comparing the process variation with first embodiment; Said first fluid connecting tube 254 also has oil separator naturally and flows into part 258 and flow out part 60 with an oil separator, wherein oil separator flow out part 60 and its first describe among the embodiment the position is set and function is consistent; Oil separator flows into part 258 and can be set at first end 262 (chiller plant is not shown in the drawings with chiller plant; The those skilled in the art that are designed to basically of chiller plant and refrigerating circuit know) in the fluid passage between the low pressure chamber 205.In this way; The oil that is arranged in the refrigerant pipe of chiller plant is (after the process compression process; Oil gets in the refrigerant pipe of the chiller plant with compressor 200 through hyperbaric chamber 48) flow out from the low pressure chamber of chiller plant; Through passing back into the engine room 14 of compressor 200 behind the oil strainer 56, chiller plant same (similar engine room 14) comprises the chamber of chiller plant.For this purpose, second end 64 that the oil separator of first fluid connecting tube 254 flows into part 258 and oil separator 66 fluids that enter the mouth are communicated with, with similar among first embodiment.The low pressure chamber 205 of chiller plant is the low-pressure section of refrigerant pipe, just the part between the suction chamber 46 of the diffusion part of chiller plant and compressor 200.In described embodiment; First end 262 of first fluid connecting tube 254 be located at being communicated with segment fluid flow between the vaporizer of refrigerant pipe at the diffusion part of chiller plant; Based on this design, oil gets into refrigerant pipe can realize the lubricated of compressor 200.
Adjust through opening or closing compressor 200 according to the quantity delivered among compressor second embodiment of the present invention; Like this; Can use pressure pump 100 to carry because desirable situation (preferably approaching constant), particularly desirable can be to treating that fuel feeding is carried out in the lubricating point zone through selecting suitable the first, the second and three-fluid connecting tube 54; 74,104 through-flow speed realizes.Through-flow speed; Be defined as refrigeration agent/refrigeration agent-mixed oil/oil and flow through each fluid connecting tube 54 in the time in each unit; The size of 74,104 amount can be passed through such as changing fluid connecting tube 54; The geometrical shape of 74,104 cross section and/or select suitable injection syringe 84 to realize.Another kind of alternative mode is, provide in this embodiment point on the cross-section that maybe can reduce that reduced (for example aperture, valve) be self-evident also be feasible.
In a second embodiment; The second fluid connecting tube 74 is communicated with opening fluid between the inlet 206 of the power supply cabin of the lubricant oil service 208 of tubulose; Lubricant oil service 208 successively with clutch shaft bearing 30, first sealed member 28 between fluid be communicated with, with the optimum Working of the lubricated and sealed member 28 of realizing clutch shaft bearing 30.What can self-evidently expect is to have a plurality of power supply cabins of being communicated with the second fluid line fluid according to compressor of the present invention to enter the mouth that a plurality of lubricating point zones of treating obtain lubricating of oiling agent in 208, the second fluid lines.Such consideration is equally applicable to first embodiment.Selectively or extraly, what can expect is that power supply cabin inlet 208 (in first embodiment, being 108) will for example be communicated with a plurality of lubricating point regional fluids of treating through (correspondingly configured or bifurcated) lubricant oil service 208.The lubricating point zone of treating in compressor 200 provides oil to supply to occur in similarly among first embodiment.
In the embodiment of two descriptions; Also in selectable other embodiments; Therefore the integral body of parts of oil strainer 56 (such as other constituent elements of oil separator shell 94 and/or striking plate 98 and/or oil strainer 56) or oil strainer 56 adopt a step operation of shell production process to accomplish such as casting with the compressor case moulding.The same mode of production can be applicable to the first, the second and three-fluid pipeline 54,74,104,254, can partly or integrally be shaped together with compressor case, also can be provided with or be formed in the compressor case.
The object of the invention not only comprises compressor 10; 200 ins and outs according to the present invention's design; Also comprise ins and outs that have the chiller plant of refrigeration pipe accordingly, chiller plant has a high pressure side (hyperbaric chamber) and a low pressure chamber (low pressure chamber 205), also has according to compressor 10 of the present invention; 200, defined as the Patent right requirement of describing and adding by above-mentioned picture.Those skilled in the art are familiar with other constituent elementss (condenser, proliferation part and vaporizer) of refrigerating machine, and more details are described hereinbefore.
What it is pointed out that here that self-evident ground can expect is that oil separator 56 needs not be centrifugal oil separator, can be other any oil separators, for example has the oil separator of filter body or filter element.Generally speaking, several argumentation points need be reaffirmed one time below:
